Zoo Hippo Welfare - Thermoregulation and Space

Welfare considerations for hippopotamuses in zoo settings, including water depth requirements and social groupings.

Key Facts

Hippos spend up to 16 hours daily submerged in water to prevent skin desiccation and regulate temperature
Hippo skin produces a natural red moisture-regulating substance (blood sweat) that functions as sunscreen and antiseptic
Wild hippo groups are territorially structured with dominant males; captive groups require careful management
Aggressive interactions in hippos can be fatal; compatible group composition requires careful assessment
Pool depth allowing full submersion and floatation is a minimum welfare requirement for captive hippos
